10 Claims. (01. 263-117 7 The object of myinvention'istoprovideadjusting hardware for sashes and the like, which is simple, durable and comparatively inexpensive to manufacture, the present application being a continuation in-part of my-copendingapplication Serial No. 693,775, filed October 16th, 1933.

A -further object is to provide adjusting hardware includinga flexible chain which can bend to some extent in one direction, but 'which'is limited against bending 'in'the other direction so that one end of it can be'c-onnectedwith the sash and the other-end can extend into the window frame, with the-weight of thechainintermediate the sash and frame tending to maintain the chain in a rigid straight position so that operator mechanism can -coa-ct with it and either push or'pull it for opening orclosingthe sash, -as desired.

Another object is to provide a chain of this character-so that the part-of 'it'which at'any time is not extended from the window frameto-the sash, can be changed in direction and thereby be concealed in a perpendicular recess in the window frame.

Another object is to provide "a connector for connecting the outer end of 'the chain-like element with the sash in such manner'asttoholdthe outer link of the chain'against'bendingiineither direction, so as to thereby retainthe portion 'of the chain intermediate the sash and the frame in rigid position for eitherthrusting or pulling even'thoughthe weight of the chain is; not operable to-retainitstraight.

Still a further object is*to-providean-actuator for moving the chain longitudinally,'which actuator is readily operable 'bymezins extending from'the insidesurface of the window frame.

A further object is to provideactuators tforithe chain in the form of a worm or a sprocket-coactingtherewith, whereby rotation of the worm or sprocket will actuate the chain to;impartjlongitudinal movement'thereto, means .alsobeingprovided, if desired, to lock the chain inanyposi'; tion to which it is adjusted. I

Another object is to provide:aformoiconstruction in which the operator ispivoted to zthe twindow-frame to accommodate. a; sash zhingedcin the ordinary manner.

for pivot pins used when assembling successive links of-the chain together.

With these and-other objects in view my invention consists in the construction, arrangement and combination 'of the various parts of my 'deviceywhereby the objects contemplated are'attained,,as hereinafter morefully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in'which:

A sash Ais provided and may be mountediiin any manner. Preferably it ismounted as shown in my copending application so that one edge;

thereof travels in a straight line at right angles tc rthe plane of the window frame. This can be accomplished by means of brackets 54 having rollers 62 adapted to coact with tracks 60 and link connections including links 68. The links;

68 are pivoted at one end to the window frame and at the other end to the sash A adjacent the center thereof.

During the opening movement of the sash, its:

center will be guided outwardly, while its left edge will be guided by the rollers 62 and the track 60. Theresultantmotion of theopening or right hand edge of the sash due to being guided by the hinge arm 68 and the track 68, will housing,l6, a flexible chain-like element 18 and a be substantially a straight line outwardly perpendicular to the plane of the window frame and in line with the inner face of the right hand side jamb. It is important that the hinge mechanism; provide a straight line motion for this edgeof the sash since my preferred form of operating mechanism must operate substantiallyin a.straight linemotion and in the path just described. I I V I provide an operator B, shown in Figures 1 to 5; inclusive, for swinging the'sash A outwardly and holding it in any desired position to which it ;isswung. The operator B includes a split a worm 86. The housing 16 is illustrated applied to the right hand side j amb l0 and mounted flush with the stops 38 which extend from the sill I2 to the housing 16, thus placing the housing 16 in a countersunk position with its face flush with the faces of the stops 38. Thetwo partsof the split; housing 16 are held together by screws'8 Z which at the same time anchor the casing to the side lambs. I I v ,Within the. housing 16, a pairof guides 84 is provided which guide the chain-like element 18 overa ninety. degree bend. Thus one end of the chain [8 can extend horizontally outward to the -sas h-A, while the other end can hang vertically downward, thelower stop 38 having .a groove i8 6;to.receive ;and conceal the down hangingend permit the chain to flex orbend in one direction I as around the curved part of the lowerguide84 in FigureS, but prevent it from bending between he hou i and t e a The outer end of, thechain with abracket 94 associated with the outer link .2; o Pr v t t c ai r nd n 1*, er down and it is allowed pivotal movement h ori zontally by a verti calpin 96 mounted in a bracket 98 secured to the sash A. The vertical pivot pin: BBpermits swinging of the sash A relative to the; chain l8 during the adjusting of the sash. Each of thelinks 92 is provided .witha groove loo in the back thereof with which teeth I82 r m t'o Figure 4, a window frame is illus- I trated having side jambs l0 and a sill l2.

the shank of the crank extends.

18' is provided,

the worm coact. It is therefore obvious that rotation of the worm will cause longitudinal If the pitch of the teeth N32 is too great to prevent' the worm from holding the chain 18 1 against movement after once being adjusted, a

lock can be provided, which in Figures 1 and 2 I have illustrated as a form of brake band H4 normally loose enough to permit rotation of the worm 80; but being tightenable therearound by screwing'a lock screw H6 inwardly." I

It will be noted that both sides of the housing 16 are threaded, as at H8, and. the'brake fband can be rotated in; either direction (clockwise to 3.

close thewindow and counterclockwise to open it). I v

Duringthe rotationof the worm 86, the chain 18 will be retracted or expelled into or from the left hand side'of the housing 16 in Figure l, while 3 the innerend of the chain will'be expelledr or retracted from the bottom of the casing and at the same time move longitudinally of the groove 86 in the stop 38. The screen stop 361s provided with a notch .120 (see Figure 5) for the chain. 18 to extend throughh The screen stop conceals this part of the chain andthe chain can be adjusted from the inside of the window frame without removing or otherwise disturbing the screen. With theparts of the adjusting hardware be' ing concealedasalready described, a neat all:

left hand side of 2;

pearance is given to the entire assembly and thus In -Figure-6,,I show howra sash canjbe hinged'at l34 in the ordinary mannerand an operator B; canbe hinged, as at l36,so.as to swing and thereby permit the right edgeof the In Figure 7, 1 show how the Worm 88 can be' dispensed with; A housing 16c is provided which serves'merely as aguide for guiding a chain through a quarter turn. I The depending endof the chain is provided with an operating handle 6 158 extending through a slotted plate I65 on a stop 380. In addition to this, any suitable means canjbe provided for locking. the chain inlany' adjusted position? 5 It will benoted that I have located the adjust- 3; ing hardware substantially midway between the 1 topand bottom of the window frame. This is the most advantageous position'for it'as anywind pressure against the sash is thereby balanced instead ofbeing greater above or below the adjustor hardware when it is mounted at the top or bottom of the: window. 'The position I illustrate is the point of greatest. mechanical 'ad-' vantage. I

sash to swingon an arc rather than travel in a r 6 straight line.

Cal

In vEnsures l to 15 inclusive. I have shown an improved type of adjustor hardware. It consists of a split casing-I10 having a chain C of sheet metal construction. The links of the chain C are made of blanks shown in Figure 14 having slots I12 in their webs vand perforations I14 in their flanges.

The .slots are for a tooth I16 of a worm I18, while the perforations are for pivot pins I80.

'The blank shown in Figure 14 is formed to the shape illustrated in Figure 13 by bending at right angles on the lines I82 and at slight angles on the lines Hi l. This makes the link channelshaped and provides the flanges at one end spaced closer together than at the other end so that. the flanges at the first end can fit between the second flanges of the next link. The ends of the webs, as indicated at I86, serve as shoulders to. engage each other to prevent fiexion of the chain in one direction, although the chain is permitted to flex in the opposite direction.

Some parts of Figures 9 to 15 are similar to parts of Figures 1 to 5. These parts are given the same reference numerals with the addition .of .the distinguishing characteristic (1. Instead of the brake band-like friction device II I, friction blocks I88 can be provided for engaging opposite sides of a sleeve I90 which extends from the worm I18. Screws I92 and I94 are illustrated for adjusting these blocks toward each other for thus increasing their friction on the sleeve I90. The screws I92 and I94 may be ordinary counter- .sunk 'head screws or one of them may be knurled as shown in Figure 10 for convenience in adjusting the friction blocks.

.Theiend of theichain attached to the sash A is illustrated in Figure 12. The means of attachment comprises a countersunk bracket I96 having a vertical pin I98 to which is pivoted a block 20!! forpivotal connection with the end of the chain.

In Figure 15, Ihave shown the guide means for the chain C. It consists of top and bottom walls2i'i2pand2iiii and side walls 266. The ends of this wall assembly are confined in openings 208 of the casing III), while the intermediate portions thereof are provided with extensions ZIII shouldered, extended through openings in the side of the casing I III and riveted as indicated at 2 I2. The side walls 206 are provided with longitudinally arranged grooves 2| 4 to accommodate the riveted ends of the pivot pins I80 of the chain C.

The casing I10 is preferably provided with shoulders 2H5. These are aligned with screen stop shoulders 2I3 of side jamb stop strips 220, the lower one having a groove 2I9 similar to the groove 86 in the stop 38 for receiving the chain. Thus the enlarged part of the casing I10 for accommodating the worm I78 forms a continuation of a portion of the strip 22!], making a neater looking flush mounted operator casing.

Some changes may be made in the construction and arrangement of the parts of my device passing .through said casing, said operator coactingtherewith to retract and expel said chainlike member upon movement of said operator, said casing being symmetrical in structure to facilitate .right or left hand application, each of the two opposite faces thereof being formed with a projection to align with said stop strip on the face of the frame member and form a continuation thereof so said casing may be mortised into said frame to form a smooth surface flush therewith and with said stop strip.
